The Galactica saga is a story that
mixes, science with legend, and the possible with the
impossible. Throughout the saga we see fuel burning
consistantly as the Galactica goes through space. This is
illogical because a thing once in motion will stay in
motion unless something stops it. In the outer reaches of
space where gravity does not exist nothing would stop a
ship from continuing forward regardless of rather fuel
continues to shoot out the back or not. In reality where
the Galactica expends fuel to maintain its speed in the
saga the ship would actually be accelerating. If there is
no gravity or resistance to motion if you are at one
speed and you then expend energy you will accelerate to a
new speed and not just maintain the speed you were at.
Illogical virtues are the hallmark of any good Sci-fi
show as the reasonable and the logical is seldom the most
interesting thing to see or experience. The most
illogical element of all are the Cylons themselves.

The
Cylons pilot their own craft rather than use computers.
And if computers can not pilot Cylon craft why can't they
be piloted by one and not three robotic machines? If
humans can pilot a more advanced fighter with one pilot
why can' t more efficient machines pilot a single craft
all by themselves? The Cylons themselves alert enemies to
their presence with a loud blaring whirling sound as a
light beam moves from one side to the other on their
visor. Why the noise would exist is a question begged to
be asked for one thing? But even more puzzingly is how
the Cylon Centurian seems to make more noise than an
entire Cylon Raider ship with the ability to escape
planetary gravitational forces. The Cylon Raider glides
silently across planetary structures while the Cylon
Centurian's whooming red eye can be heard anywhere and
everywhere. Throughout the saga Cylons are seen marching
about with sheathed swords yet Cylons are never seen
reloading/recharging their laser rifles during the show.
Why carry a sword when you never run out of ammo for your
ranged weapon? Cylon ships have little as far as lighting
to help guide them in space but Cylon Centurians with
their red visor eye and shiny armor practically light up
the sky. If a spaceship doesen't need much light to guide
itself in space why would a Cylon Centurian?

If Cylons can be created at will, why are the average
Cylon Centurians given so little intelligence? If
processing technology exists would a machine race really
reserve the best technology for certain machines and not
others? It seems silly to have super intelligent IL
Series droids, and then have dumb as hell machines
everywhere else. If programming can't set a command
structure then why would lack of intelligence be used to
determine social command structures?

The Colonial Fleet has its share of illogical fallacies as
well. Despite a shortage of spaceworthy vessels to carry human
survivors into space there is room to carry murderers and
cutthroats in special prison barges. The Battlestars have
missiles but the only real time they are used is in close combat
between the Battlestar Pegusus and a trio of Basetars. Aren't
missiles supposed to be long range weapons? A mine field in one
episode has to be destroyed rather than gone around inspite of
how large space is and how easy such dangers would be to just go
around. The fleet deals with food shortages in some episodes yet
we seldom see methods of waste recycling or active farmers
planting things. Further the crew is often seen drinking and
partying with alcohol as if food was never a concern.
